APPARATUS FOR DISPLAYING ADVERTISEMENTS.

To all whom it may concern:

Be it known that I, GEORGE HOLT THOMAS, gentleman, a subject of the Kingof Great Britain, residing at Bookham Cottage, Great Bookham, in thecounty of Surrey, England, have invented new and useful Improvements inApparatus for Displaying Advertisements, of which the following isspecification.

According to this invention a number of vertical sheets of flexiblematerial such as anvas are fixed together along a central. horizontalline while their top and bottom edges carry weighted bars, means beingprovided for raising the bottom bars and for periodically releasing thetop bar of the sheet which happens to be in front, thus allowing it tofall to the bottom and expose a fresh surface to view.

A convenient way of working the apparatus is to provide at the back ofthe sheets continuously moving endless chains carrying hooks or lifterswhich come beneath the back bottom bar and gradually raise it until itreaches the top and pushes the front top bar out of its retainingdevices and allows it to fall.

The retaining devices may consist of suitable springs.

Figure 1 is a front elevation (with half the case removed) of anapparatus constructed according to this invention. Fig. 2 is a sectionon the line 22 Fig. 1. Fig. 3 is a section on the line 3-3 of Fig. 1.

a is a case having a window 6 through which the advertisements are seen.

a are sheets of flexible material fixed together along the line 0 andhaving their ends fixed to bars 0 The ends of the bars 0 are grooved andmove between guide plates (Z d, the plates cl being fixed directlySpecification of Letters Patent.

to the sides of the case while the plates cl are carried by blocks (Zfixed to them.

6 are endless chains driven by gearing from a motor 7 as shown.

0 are carriers fixed to the chains which when in their lowest positioncome beneath the back bottom bar 0 and then as they ascend lift it andultimately force it past the retaining springs g and in so doing forcethe front top bar 0 past the spring bolts 7L and allow it to drop. 1

What ll claim is 1. Apparatus for displaying advertisements consistingof the combination of a number of sheets of flexible material fixedtogether along a central horizontal line and having weighted bars fixedto their top and bottom edges, and means for raising the bottom bars andperiodically releasing the top bar of the sheet which happens to be infront.

2. Apparatus for displaying advertisements, consisting of thecombination of a number of sheets of flexible material fixed togetheralong a central horizontal line and having weighted bars fixed to theirtop and bottom edges, guides for the bars, an endless band carryingdevices for raising the bars to the top of the apparatus, means forretaining the raised bars, and means for operating the endless band tolift a bar from the bottom of the apparatus to the top thereof and tocause said bar to move the top bar of the sheet which happens to be infront forward in the guides to allow it to drop.
